Sites as apps and games

Your start page is a launcher

Every bookmark is a tile on the start page. Open it as a site, as an app without the browser around it, or as a game in game mode.

Filter by sites, apps, games or your own tags, sort by hand, by name or by last opened, and lay it out as a grid or a list in three sizes.

Every bookmark keeps its own settings, from the user agent and dark mode to game mode, and closing an app or a game takes you back to the start page.

The start page: bookmarks as site, app and game tiles under filter tabs, the search field at the bottom

itch.io's HTML5 games opened as an app, with no browser toolbar — itch.io as an app

A bookmark's options in Quick Access: open, launch as game, rename, tags, move, remove — Launch as site, app or game

The start page as a list: each bookmark with its site, launch badge and tags — List layout with tags

Game mode

Play browser games from itch.io and similar sites, with WebGL 2, gamepad and audio.

Game mode hides the browser and routes input directly to the page. Input maps let you map controls to keyboard keys, mouse or gamepad input, with an editor built in.

It can also cut the game out of the page, fit it pixel-perfectly to the screen and apply CRT, LCD or upscaling shaders.

Built for any input

Gamepad, keyboard and touch

A virtual cursor on the stick or D-pad, Vimium-style link hints that label every link with the buttons or keys that open it, and an on-screen keyboard as a grid or a wheel.

Every browser action can be bound to a gamepad gesture or a keyboard shortcut, in the app, with tap, hold and chord. On phones and e-readers, touch taps and scrolls the page.

The wheel keyboard: letters in groups around a center, picked with the stick and typed with the face buttons — Wheel keyboard

The button bindings: each browser action with its gamepad and keyboard gestures — Button bindings

Read in comfort

Made for small screens

Reader view strips pages down to their articles, even logged-in and dynamic ones.

Dark pages use sites' own dark themes, or force dark on sites that have none. Page zoom from 50% to 300% reflows the layout, per tab.

Ads and trackers are blocked at the network level with Brave's adblock-rust, EasyList and EasyPrivacy.
